FATTY ALCOHOL Resistant O-Rings and Seals

Fatty acids and fatty alcohols are both types of lipids, which are molecules that make up the cell membranes of living organisms. Fatty acids are composed of a carboxyl group attached to a hydrocarbon chain, while fatty alcohols are composed of an alcohol group attached to a hydrocarbon chain. Common uses of fatty acids include as an emulsifier in food products, as a surfactant in cleaning products, and in the manufacture of soaps and cosmetics. Common uses of fatty alcohols include as a lubricant and lubricity additive, as a thickening or gelling agent in foods and personal care products, and as a surfactant and emulsifier in industrial products.

When rubber is exposed to fatty acids or fatty alcohols, it can cause the rubber to swell, become brittle, and crack. This can result in a decrease in the rubber's mechanical strength and resilience, leading to premature failure and reduced service life. Additionally, the swelling of the rubber can cause it to swell away from seals and gaskets, leading to leaks.
